By Gayle-Lussac's law, the pressure and temperature of a fixed volume and amount of gas is directly proportional.
Thus,
P/T = constant
So if the temperature is increased four times, the pressure is also increased four times.
In the technique of recrystallization "the mother liquor is the filtrate".
<u>Option: </u>C
<u>Explanation:</u>
The portion of a solution remaining over after crystallization is understood as a mother liquor. It is found in chemical reactions that include sugar refining. It is the liquid produced by filtration of the crystals. The residual liquid, once the crystals have been extracted out as the mother liquor will include a portion of the initial solution as estimated at that temperature by its solubility as well as any unfiltered contaminants. Second and third crystal crops can then be collected from the mother's liquor.
Answer:
0.165
Explanation:
Feel free to let me know if this is wrong because I have seen the question before but cannot really remember!
Graphite and diamond come under covalent structure.
Answer:
1. LiCi is formed by the treatment of lithium carbonate with hydrochloric acid
2. A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).
3. Chemical decomposition, or chemical breakdown, is the process or effect of simplifying a single chemical entity into two or more fragments.
4. A single-displacement reaction, also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound
5. Double replacement reactions have two ionic compounds that are exchanging anions or cations.
6. The most electronegative elements are found on the top right of the periodic table.
7. cesium
8. Electronegativity describes the degree to which an atom attracts electrons in a chemical bond. But the electronegativity of two atoms would determine their bond type.
9. ionic bond
10. polar covalent bond
11. fluorine
12. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change.
Hope i was able to help!!!
